I'm still stoking my 642 with 125gr. +P Golden Sabers but I plan on trying out the 158gr. +P LSWCHP when payday rolls around. If nothing else, it seems a tad more affordable than the "wonder bullets."
Wife and I are going on a few day/overnight trips this weekend so I'm planning on carrying both my Mil-Spec in it's Max-Con V and the 642 in the DeSantis ankle holster - you can never have enough firepower when travelling.
